Two American climbers have successfully skied down from the summit of the world’s fourth-highest mountain, organisers said on Monday.

James Morrison of Tahoe, California, and Hilaree Nelson of Telluride, Colorado, scaled Mount Lhotse’s 8,516-metre summit on Sunday with two other climbers and three Nepalese Sherpa guides, said Pemba Sherpa of Xtreme Climbers Treks and Expeditions.
